How is multiple inheritance supported in Java?a.Virtual base classb.Final classc.Abstract classd.Interface

Multiple inheritance in Java is supported through the use of interfaces.

Here's a step-by-step explanation:

1. In Java, a class can implement multiple interfaces. This is how Java supports the concept of multiple inheritance.

2. An interface in Java is a completely abstract class that contains only abstract methods. Some of these methods are public, static, and final.

3. When a class implements an interface, it inherits the abstract methods of the interface.

4. A class can implement multiple interfaces, thereby 'inheriting' the methods from all the interfaces. This is essentially how multiple inheritance is achieved in Java.

So, the correct answer to your question is d. Interface.
